Description

Technical Field

[0001] The invention relates to the technical field of portable alarm devices, and in particular to a small sound-generating structure with a lighting function. Background Art

[0002] In outdoor activities (such as mountaineering, camping, night running) or special working environments (such as construction sites, mines), rapid warning in emergency situations is crucial.

[0003] The traditional alarm device has a single function and only relies on sound or light, which makes it difficult to effectively transmit warning signals in complex environments. For example, the prior art discloses a Chinese invention such as the announcement number CN216927772U and the patent name of the emergency alarm for personal self-defense, which specifically discloses an alarm body and an alarm plug installed on the alarm body. The alarm plug is movably connected to the alarm body and is semi-pull-out and plug-in through a limiting structure respectively provided on the two. The limiting structure includes a limiting block provided on the alarm body and a limiting groove provided on the alarm plug and cooperates with the limiting block to achieve limiting. The emergency alarm for personal self-defense provided by the present application does not need to reset the alarm plug to the alarm body, so that the user can quickly reset the alarm.

[0004] In life, it is inevitable to encounter some emergency situations, so the functionality and portability of the alarm device are crucial. Although the above-mentioned equipment can send out alarm sounds, if the lighting environment is poor and it is in a very open place, the alarm function of the alarm sound alone will not be very good. The overall functionality is poor and the alarm function is single.

[0005] Therefore, a small sound-generating structure with lighting function is proposed to solve the above-mentioned problems. Summary of the invention

[0011] Furthermore, the shell is a hexahedral structure.

[0012] Furthermore, the lighting lamp panel and the sound-generating component are distributed on two opposite outer end surfaces of the shell.

[0013] Furthermore, the shell is provided with a plug-in switch for controlling the on and off of the sound module and a lighting switch for controlling the on and off of the lighting module.

[0014] Furthermore, the plug switch is installed at any vertex of the housing.

[0015] Furthermore, the sound-generating component includes a vibrating ceramic sound-generating structure, and the vibrating ceramic sound-generating structure includes a piezoelectric ceramic sheet.

[0016] Furthermore, the sound-emitting component includes a sound amplification structure, which is composed of a first sound amplification structure and a second sound amplification structure. A sound guide hole is opened in the middle of the first sound amplification structure, and two first sound guide rings with different heights and concentrically distributed with the sound guide hole are arranged at one end of the first sound amplification structure.

[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Embodiment 1:

[0041] See attached Figure 1-9 This case proposes a small sound-emitting structure with lighting function, including a shell 1 with a regular hexahedron structure, with a side length of about 8 cm, made of high-strength ABS plastic, and has waterproof and drop-proof properties. The shape of the shell 1 is not specifically limited and can be held in hand or carried around during normal use.

[0042] An illumination lamp panel 10 and a sound-emitting component 11 are provided on the outer end face of the shell 1. In the present embodiment, the illumination lamp panel 10 adopts an LED panel lamp structure. An illumination switch 13 for controlling the opening and closing of the illumination module is provided on one side of the shell body of the shell 1. The illumination lamp panel 10 is opened and closed by pressing the illumination switch 13.

[0043] Not only can it be used as a common lighting device, but also when in an open area with poor lighting conditions, the device can emit sound and light at the same time.

[0044] In this embodiment, a circuit board 2 is disposed inside the housing 1 , and at least a sound module electrically connected to the lighting lamp panel 10 and a lighting module electrically connected to the sound generating member 11 are integrated on the circuit board 2 .

[0045] In addition, a lithium battery storage unit is provided in the shell 1 and is electrically connected to the circuit board 2 and is used to supply power to the lighting panel 10 and the sound-emitting component 11. A charging hole is provided on one side end face of the shell 1 to charge the lithium battery storage unit through an external power supply.

[0046] It should be noted that a pluggable waterproof plug is provided in the charging hole, one side of which is fixed on the housing 1. During normal use, the waterproof plug is inserted into the charging hole to prevent water from entering the internal components.

[0047] It is worth noting that in this embodiment, the lighting panel 10 and the sounding member 11 are distributed on two opposite outer end surfaces of the shell 1, that is, the directions of the lighting panel 10 and the sounding member 11 can be determined by rotating the shell 1 according to actual needs.

[0048] The housing 1 is also provided with a plug-in switch 12 for controlling the opening and closing of the sound module. When encountering danger, the plug-in switch 12 can be pulled to start the sound module, and then the sound component 11 can emit a loud sound to warn.

[0049] In order to facilitate tearing and avoid accidental touching, the plug-and-unplug switch 12 is installed at any vertex of the housing 1 .

[0050] In this embodiment, the sound-generating member 11 includes a vibrating ceramic sound-generating structure 111 and a sound-enhancing structure 113. The vibrating ceramic sound-generating structure 111 includes a piezoelectric ceramic sheet 112. The principle of vibration sound generation is a well-known technology and will not be described in detail here. In this embodiment, a vibration motor is integrated on the circuit board 2 to strike the piezoelectric ceramic sheet 112 at high speed to generate sound. The piezoelectric ceramic sheet 112 vibrates to generate high-frequency sound waves, which are reflected and amplified by the "maze structure" formed by the sound guide hole 1133 and the sound guide ring (see Figure 5-9 ), the output sound pressure level reaches 110dB and the coverage range reaches 50 meters.

[0051] In order to make the sound more powerful and loud, the piezoelectric ceramic sheet 112 is flat and parallel to the front and rear end surfaces of the shell 1, and the sound amplification structure 113 is arranged between the piezoelectric ceramic sheet 112 and the outer end surface of the shell 1.

[0052] It should be noted that the sound amplifying structure 113 includes a first sound amplifying structure 1131 and a second sound amplifying structure 1132. A sound guide hole 1133 is opened in the middle of the first sound amplifying structure 1131. The sound emitted from the piezoelectric ceramic piece 112 will be dispersed through the sound guide hole 1133, and one end of the first sound amplifying structure 1131 is arranged opposite to the piezoelectric ceramic piece 112.

[0053] The other end of the first sound amplifying structure 1131 is provided with two first sound guide rings 1134 which are concentrically distributed with the sound guide hole 1133 and have different heights. The second sound amplifying structure 1132 is arranged between the first sound amplifying structure 1131 and the outer end surface of the shell 1. The second sound amplifying structure 1132 is provided with a second sound guide ring 1135 at one end facing the first sound amplifying structure 1131. The second sound guide ring 1135 is concentrically distributed with the two first sound guide rings 1134 and is staggered. Thus, the "maze structure" formed by the two first sound guide rings 1134 and the second sound guide ring 1135 will cause the sound to be reflected multiple times, making the sound thicker.

[0054] One end of the second sound amplifying structure 1132 away from the first sound amplifying structure 1131 is curved, and the housing 1 has a plurality of sound-permeable holes 14 at one end facing the curved surface of the second sound amplifying structure 1132, through which sound is emitted, ensuring uniform sound diffusion.

[0055] Embodiment 2:

[0056] This embodiment is based on the above-mentioned embodiment 1 and proposes the following scenarios of applying the device in embodiment 1.

[0057] For example, outdoor night emergency lighting and alarm. When a climber gets lost at night, he needs to illuminate the path and send out a distress signal at the same time. First, press the lighting switch 13 to turn on the LED light panel to provide continuous lighting (lasting about 6 hours). In an emergency, unplug the plug switch 12 to trigger the sound module. The device continues to emit a high-frequency alarm to attract the attention of rescuers.

[0058] For example, it can serve as a safety warning in a construction site. When workers are working in a confined space, they need to quickly alert the outside world to sudden dangers (such as landslides). First, the device is fixed on a safety helmet or a tool bag, and the lighting panel 10 provides local lighting forward. When in danger, pull out the plug switch 12, and the sound and light are started synchronously, penetrating the noisy environment to transmit a warning signal.

[0059] Another example is that it can be applied in personal self-defense. When a woman walks alone at night, she can carry the device as a self-defense tool and use it as a flashlight (lighting mode) during daily walking. When threatened, she can quickly unplug the switch 12 to trigger a high-decibel alarm to deter attackers and attract the attention of passers-by.

[0060] The product in this embodiment can not only provide dual-mode sound and light warnings to meet the needs of complex environments, but also has a compact overall structure (weight is only 150g), is waterproof and drop-proof, and is suitable for extreme outdoor conditions. In addition, the sound wave propagation (maze structure) after the sound guide ring structure is optimized can effectively enhance the warning range and clarity.

[0061] In addition, this product uses a rechargeable lithium battery, which supports 6 hours of continuous lighting or 8 hours of intermittent alarm, meeting the needs of long-term use.

[0062] It solves the problem of single function and poor environmental adaptability of traditional alarm devices, and has significant practical value in the fields of outdoor emergency, industrial safety and personal protection. Its sound and light coordinated design, portable operation and reliable performance make it an efficient and multi-functional warning tool in emergency situations.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
